300-445 Question 137
Select 2Your enterprise network is experiencing intermittent performance issues for a critical web-based application hosted on a private data center. You are tasked with designing a solution to monitor the application’s availability and performance, ensuring end-to-end user experience from multiple geographic locations. Which of the following options would be most effective for implementing web-based network assurance in this scenario?
- A
Deploy synthetic transaction monitoring to simulate user interactions with the application from various geographic locations.
- B
Use a web application firewall (WAF) to block external threats and monitor application traffic.
- C
Implement deep packet inspection (DPI) to capture and analyze web traffic for performance bottlenecks.
- D
Leverage Real User Monitoring (RUM) to track actual user interactions and measure their experience in real time.
- E
Use SNMP-based monitoring to track CPU and memory usage on the application servers.
Show answer and explanation
Correct answers: A, D
Explanation
To ensure effective web-based network assurance, it is crucial to monitor both simulated and actual user interactions with the web application. Synthetic transaction monitoring provides a proactive approach to detect issues by simulating user activity, while Real User Monitoring (RUM) captures real-time user experience data, offering a comprehensive view of application performance across geographic locations. Other approaches, such as WAF, DPI, and SNMP, serve different purposes and are less effective in addressing the specific need for end-to-end user experience monitoring.
- A. Correct.
Synthetic transaction monitoring is effective for simulating user interactions with the application from various locations, providing insights into response times and availability.
- B. Incorrect.
A web application firewall (WAF) focuses on security by protecting against threats like SQL injection and cross-site scripting, but it does not provide detailed insights into application performance or user experience.
- C. Incorrect.
Deep packet inspection (DPI) is useful for analyzing network traffic in detail, but it is not specifically designed for monitoring web application availability or end-to-end user experience.
- D. Correct.
Real User Monitoring (RUM) is essential for tracking actual user interactions and measuring their experience in real-time, making it a critical component of web-based network assurance.
- E. Incorrect.
SNMP-based monitoring is valuable for tracking infrastructure performance metrics, like CPU and memory usage, but it does not provide visibility into web application performance or user experience.
